Injectable muscle relaxants are the most requested aesthetic treatments for smoothing dynamic wrinkles. This guide covers how they work, what to expect, and how to choose the right product for your needs.
Injectable muscle relaxants represent one of the most effective non-surgical approaches to addressing facial lines caused by repetitive muscle movements. Whether you call it Botox, Dysport, Xeomin, or a generic neuromodulator, these treatments work on the same principle: temporarily relaxing the muscles that create expression lines.
How Injectable Muscle Relaxants Work
Injectable muscle relaxants contain botulinum toxin type A, a purified protein that blocks nerve signals to targeted facial muscles. When these muscles cannot contract as strongly, the lines and wrinkles they create soften or disappear. The results are temporary—typically lasting 3 to 6 months—because the body gradually regenerates the nerve connections.
Common Injectable Muscle Relaxant Options
Botox (Onabotulinumtoxin A): The most widely recognized brand, Botox has been FDA-approved since 2002. It is highly effective, reliable, and the clinical reference standard.
Dysport (Abobotulinumtoxin A): Similar to Botox, Dysport tends to diffuse slightly more, making it an excellent choice for larger areas. Some practitioners prefer it for forehead lines.
Xeomin (Incobotulinumtoxin A): A newer option that requires no additives. Some patients report fewer antibodies forming, though clinical evidence is mixed.
Treatment Areas
- Forehead lines (horizontal wrinkles from raising eyebrows)
- Frown lines (vertical lines between eyebrows)
- Crow's feet (lines radiating from the outer eyes)
- Bunny lines (creases on the nose bridge)
- Lip lines (vertical lines above the upper lip)
- Jaw slimming (masseter reduction for V-shaped face)
- Excessive sweating (hyperhidrosis in underarms, palms, feet)
What to Expect
The appointment takes 15 to 30 minutes. You will feel small pinches as the injections are administered. Results are not immediate—onset occurs around day 3 to 5, with full results by day 14. Plan your treatment 2 weeks before an important event.
Cost and Duration
Injectable muscle relaxants are typically charged per unit (usually €8–€15 per unit in Malta). A full treatment ranges from €150–€400 depending on the areas treated and the amount of product needed. Results last 3 to 6 months; most people maintain their results with touch-ups every 12 weeks.
